Tá 1 chos cothrom le 304.8 milliméadar:
1 ft = 304.8 mm
Tá 1 orlach cothrom le 25.4 milliméadar:
1 in = 25.4 mm
Tá an fad d i milliméadair (mm) cothrom leis an bhfad d i gcosa (ft) uaireanta 30.48 móide an fad d in orlach (in) huaire 25.4:
d (mm) = d (ft) × 30.48 + d (in) × 25.4
Tiontaigh 2 throigh + 3 orlach go milliméadair:
d (mm) = 2ft × 30.48 + 3in × 25.4 = 685.8mm
